Using `libbsm` in Swift with Swift Package Manager

Using Swift
1

Hello all!

I am attempting to use audit_token_to_pid from libbsm in a simple Swift package and I am getting a linker error:

Undefined symbols for architecture arm64:
  "_audit_token_to_pid", referenced from:
      _[package-name]_main in main.swift.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: fatalError

This answer from the Apple Developer Forums seems to suggest that I could just import Darwin.bsm, but that does not make the linker error go away for me.

Is there something I am missing?

EDIT: It seems I was missing this code block below in my executable target. It works now with this code block, but I'm not sure if that is a new requirement or not.

      linkerSettings: [
        .linkedLibrary("bsm")
      ]
